A radiator manufacturing customer from Pakistan selected a SUNHOPE semi-automatic radiator clinching machine to improve their radiator core assembly process.
The project was completed in 2021 and has been successfully applied in the customer’s production workshop for radiator assembly.
This case demonstrates a proven and stable solution for radiator manufacturers upgrading from manual assembly to semi-automatic production.
Project Background
Before using the machine, the customer relied on manual clinching for radiator assembly. This led to several production challenges:
1.Inconsistent clinching quality
2.Low production efficiency
3.High dependency on skilled operators
4.Limited capacity for scaling production
To improve stability and efficiency, the customer required a more reliable solution that could support daily workshop production without increasing operational complexity.
SUNHOPE recommended a semi-automatic clinching machine suitable for flexible radiator manufacturing.
Machine Overview
The semi-automatic clinching machine is designed for radiator core and header plate assembly. It combines manual operation flexibility with mechanical positioning stability, making it suitable for small and medium-scale radiator production.
The equipment was delivered in a reinforced wooden case to ensure safe international shipping.
Technical Specifications
Header plate width: ≤ 120 mm
Header plate length: ≤ 1000 mm
Core height: ≤ 1100 mm
Power supply: 220V / single phase / 370W
Air pressure: 0.6 MPa
Machine size: 1275 × 1270 × 1880 mm
Weight: 350–400 kg
Operation mode: Semi-automatic
Clinching heads: 20 mm / 40 mm
Structure: 5-cylinder rail sliding system
Clinching method: Single-side and double-side available
Key Advantages
This machine provides clear improvements compared with manual radiator clinching:
1.More stable and consistent assembly quality
2.Higher production efficiency with fewer operators
3.Flexible adjustment for different radiator sizes
4.Easy operation with short training time
5.Suitable for OEM and export radiator production
The rail-guided sliding system ensures stable movement, while adjustable clinching heads allow accurate adaptation to different production requirements.

Operation Process
1.Place radiator core into working position
2.Adjust header plate width (approx. 4 mm clearance)
3.Align using rotary adjustment table
4.Press clamping button to fix position
5.Adjust height and clinching depth
6.Perform clinching with controlled sliding movement
The system is designed for simple operation and stable repeatability in daily production.
Application Scope
This machine is widely used in:
1.Automotive radiator manufacturing factories
2.Aluminum radiator core assembly workshops
3.OEM radiator production lines
4.Small and medium batch production plants
It is especially suitable for manufacturers upgrading from manual production to semi-automatic systems.
Customer Result
After installation, the customer achieved:
1.Improved radiator assembly consistency
2.Higher production efficiency
3.Reduced reliance on skilled manual labor
4.More stable and controlled workshop production
